Gilles Peskine 35115f9c1a New algorithm PSA_ALG_RSA_PSS_ANY_SALT
This is a variant of PSA_ALG_RSA_PSS which currently has exactly the same
behavior, but is intended to have a different behavior when verifying
signatures.

In a subsequent commit, PSA_ALG_RSA_PSS will change to requiring the salt
length to be what it would produce when signing, as is currently documented,
whereas PSA_ALG_RSA_PSS_ANY_SALT will retain the current behavior of
allowing any salt length (including 0).

Changes in this commit:

* New algorithm constructor PSA_ALG_RSA_PSS_ANY_SALT.
* New predicates PSA_ALG_IS_RSA_PSS_STANDARD_SALT (corresponding to
  PSA_ALG_RSA_PSS) and PSA_ALG_IS_RSA_PSS_ANY_SALT (corresponding to
  PSA_ALG_RSA_PSS_ANY_SALT).
* Support for the new predicates in macro_collector.py (needed for
  generate_psa_constant_names).

Gilles Peskine 9b35640e3f Generate cpp_dummy_build.cpp dynamically
Generate programs/test/cpp_dummy_build.cpp dynamically instead of
maintaining it manually. This removes the need to update it when the list of
headers changes.

Include all the headers unconditionally except for the ones that cannot be
included directly.

Support this dynamic generation both with make and with cmake.

Adapt all.sh accordingly. Remove the redundant C build from
component_build_default_make_gcc_and_cxx (it was also done in
component_test_default_out_of_box), leaving a component_test_make_cxx. Also
run the C++ program, because why not. Do this in the full configuration
which may catch a bit more problems in headers.

Fixes #2570 for good.

Gilles Peskine 377a310da4 Catch failures of AES or DES operations
Declare all AES and DES functions that return int as needing to have
their result checked, and do check the result in our code.

A DES or AES block operation can fail in alternative implementations of
mbedtls_internal_aes_encrypt() (under MBEDTLS_AES_ENCRYPT_ALT),
mbedtls_internal_aes_decrypt() (under MBEDTLS_AES_DECRYPT_ALT),
mbedtls_des_crypt_ecb() (under MBEDTLS_DES_CRYPT_ECB_ALT),
mbedtls_des3_crypt_ecb() (under MBEDTLS_DES3_CRYPT_ECB_ALT).
A failure can happen if the accelerator peripheral is in a bad state.
Several block modes were not catching the error.

This commit does the following code changes, grouped together to avoid
having an intermediate commit where the build fails:

* Add MBEDTLS_CHECK_RETURN to all functions returning int in aes.h and des.h.
* Fix all places where this causes a GCC warning, indicating that our code
  was not properly checking the result of an AES operation:
    * In library code: on failure, goto exit and return ret.
    * In pkey programs: goto exit.
    * In the benchmark program: exit (not ideal since there's no error
      message, but it's what the code currently does for failures).
    * In test code: TEST_ASSERT.
* Changelog entry.

Manuel Pégourié-Gonnard 14134281df Fix bug with UDP proxy not forwarding enough
We previously introduced a safety check ensuring that if a datagram had
already been dropped twice, it would no longer be dropped or delayed
after that.

This missed an edge case: if a datagram is dropped once, it can be
delayed any number of times. Since "delay" is not defined in terms of
time (x seconds) but in terms of ordering with respect to other messages
(will be forwarded after the next message is forwarded), depending on
the RNG results this could result in an endless loop where all messages
are delayed until the next, which is itself delayed, etc. and no message
is ever forwarded.

The probability of this happening n times in a row is (1/d)^n, where d
is the value passed as delay=d, so for delay=5 and n=5 it's around 0.03%
which seems small but we still happened on such an occurrence in real
life:

    tests/ssl-opt.sh --seed 1625061502 -f 'DTLS proxy: 3d, min handshake, resumption$'

results (according to debug statements added for the investigation) in
the ClientHello of the second handshake being dropped once then delayed
5 times, after which the client stops re-trying and the test fails for
no interesting reason.

Make sure this doesn't happen again by putting a cap on the number of
times we fail to forward a given datagram immediately.
